Underwater Cleaner Filter Scraper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater cleaning machines require frequent filter changes, which is time-consuming and costly, and results in reduced suction power due to filter clogging, affecting their cleaning performance.
Innovation Solution
The underwater cleaning machine employs continuous mechanical filter cleaning using scrapers or vibrators, ensuring optimal performance by maintaining maximum water flow and preventing filter clogging, with the option of combining mechanical and fluidic cleaning principles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the filter is used continuously without cleaning, then the cleaning machine can operate for extended periods, but the filter becomes clogged with dirt reducing water flow and suction power
Solution Approach 1:
The patent implements continuous cleaning action during the filter's operation. A scraper mechanism continuously removes accumulated dirt from the filter surface while water flows through it, ensuring the filter maintains optimal permeability throughout its service life rather than degrading until replacement is needed.
Solution Approach 2:
The filter cleans itself through the integrated scraper mechanism that automatically removes dirt accumulation. The system uses the existing water flow and a driving mechanism to activate the scraper, allowing the filter to maintain its own performance without external intervention or shutdown for maintenance.
2Productivity
If the filter is cleaned frequently to maintain performance, then suction power remains optimal, but the cleaning machine must be taken out of service frequently
Solution Approach 1:
The cleaning action occurs continuously during normal operation rather than requiring periodic shutdowns. The scraper mechanism operates concurrently with water filtration, eliminating the need to stop the cleaning machine for filter maintenance and maintaining uninterrupted productivity.
Solution Approach 2:
The scraper continuously removes dirt before it significantly clogs the filter pores. By performing preventive cleaning action throughout operation, the system prevents performance degradation rather than reacting to it, maintaining optimal suction power without interruption.
3Productivity
If a mechanical cleaning system is added to clean the filter continuously, then filter performance is maintained, but the device complexity increases
Solution Approach 1:
The driving mechanism serves dual purposes: it drives the cleaning machine forward through water jets and simultaneously rotates the filter to enable the scraper to clean its surface. This multi-functionality reduces the need for separate dedicated components for each function, mitigating the increase in complexity.
Solution Approach 2:
The patent combines the filter support structure, driving mechanism, and scraper assembly into an integrated unit. The filter is mounted on a support that is directly driven by the machine's propulsion system, merging multiple functions into a single structural assembly rather than separate components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows the cleaning machine to operate continuously with optimal performance, maintaining high suction power and extending the time between filter replacements, as the filter remains clean and efficient throughout its operation.
Implementation Method 1
The scraper moves relative to the surface of the at least one filter, i.e., for example, the scraper is moved past the filter or the filter is moved past the scraper
Implementation Method 2
vibrators or vibration generators to vibrate the at least one filter
Implementation Method 3
it is advantageous if the mechanical cleaning is further supported by a counterflow principle
